Dandelion is a very powerful diuretic, its action camparable to that of the drug Frusemide. The usual effect of a drug stimulationg the kidney function is a loss of vital potassium from the body, which aggravates any cardio-vascular problem present. With Dandelion, however, we have one of the best natural sources of potassium. It thus makes an ideally balanced diuretic that may be used safely wherever such an action is needed, including in cases of water retention due to heart problems. As a cholagogue it may be used in inflammation and congestion of liver and gall-bladder. It is specific in cases of congestive jaundice. As part of a wider treatment for muscular rheumatism it can be most effective. This herb is a most valuable general tonic and perhaps the best widely applicable diuretic and liver tonic.
